Is there anything more frightening than death? Or death by another person? In the following passage, Jesus says not to fear death by another man – do not be afraid of what “they” can do to you. It is a pretty solid point to fear the one who knows the number of hairs on your head and controls where poeple go in the after life.
And I say to you, My friends, do not be afraid of those who kill the body, and after that have no more that they can do. But I will show you whom you should fear: Fear Him who, after He has killed, has power to cast into hell; yes, I say to you, fear Him! (Luke 12:4, 5 NKJV)
I believe Jesus is pursuading us to to put God first; elavate Him above all else – including our fear of death or man. We should respect Him above all other authority. That doesn’t mean we ignore all other aspects of life. But, He is the very one who created us and can give us everlasting life or everlasting hell.
Also I say to you, whoever confesses Me before men, him the Son of Man also will confess before the angels of God. But he who denies Me before men will be denied before the angels of God. (Luke 12:8, 9 NKJV)
